An anonymous poster there says he has heard that the star Betelgeuse is about to go supernova, maybe as soon as a few weeks:
Betelgeuse is about 640 light years away (give or take 140 light years) -- so, if it blows up next week, you won't know it for another 640 years ... LOL ...
I'm sure he meant 639 years and 51 weeks ago plus another week. Oh yeah...
LoL!
